TH REE-WAY RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 536,715,dated April 2,18S 5.'

Application iiled February 13, 1895. Serial No. 538,762. (No model.)

` To @ZZ whom it may concern,.-

Be it known that I, JAMES D. BAILEY, of Utica, in the county of Oneidaand State of New York, have invented certain new and useful Improvementsin Three-Way Railway- Switches; and I ldo hereby declare that thefollowing'is a full, clear, and exact description of the i-nvention,which will enable others skilled. in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the numerals of reference marked thereon, which form part of thisspecification.

My present invention relates to improvements in threeway split switches.

In the drawings which accompany and form apart of this specification andin which similar numerals of reference refer to corresponding parts inthe several views, Figure 1 shows a plan view of the switch closed. Fig.2 shows the switch in the first shift. Fig. 3 shows the switch in theposition of the second shift Fig. 4 is a side View. Fig. 5 shows a crosssection taken at the side of the shifting-bar with the railscorresponding in position to Fig. 1. Fig. 6 shows a similar sectioncorresponding to Fig. 2. Fig. 7 shows a similar section corresponding toFig. 3. Fig. 8 shows a cross section including the springs. Fig. 9 showsa modified form of construction.

Referring to the reference Iigures in a more particular description, 1and 2 indicate` stationary rails secured to ties as 3 in the usualmanner, and which rails diverge at the switch substantially as shown.Between the stationary rails at the point of divergence are located thefour movable pointed split rails 4, 5, 6 and 7. The points of the rails5 and 7 lie back of the points of rails 4 and 6. The rails 5 and (i aresecured to the shifting-bar 8 by clamps 5 and 6a respectivelygso as notto be movable in either direction along the bar. The rails 4 and 7areindependent of the shifting-bar to move in one direction, but are movedwith the shifting-bar in the other direction. This movement, so far asrail 4 is concerned, is caused by the hooked shoulder projection 9, andas to rail 7, by as similar projection l0 from the shifting-bar.

Instead of the projections 9 and 10,asleeve block 11 having fingers forengaging the rail, may be provided, which block willslide freely in onedirection on the shifting-bar and be operated on the other by a fixedcollar or shoulder piece 12.

For operating the switch rails 4 and 7 in the opposite direction fromthat to which the shifting-bar is adapted to operate them, there areprovided springs 13 and 14. These springs operate from a fixed support15 against the sliding chairs 16 and 17, respectively, whichA aresecured to the rails 4 and 7. The

springs are mounted on a rodlS which holds noted, however, that when theswitch is ady justed to the position shown in Fig. 1, which is thenormally closed position, all the rails are held positively and theswitch cannot be maliciously displaced without breaking the mechanism.In this position none of the rails are held only by springs, so that bythe use of a bar they could be sprungandblocked in dangerous position.

lVhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a three way switch, of'two diverging fixed rails,four intermediate pointed rails, a shifting bar to which the two middlemovable rails are immovably secured, and having shoulders engaging fromthe outer n sides only, the two outer movable rails and springs actingagainst the outer movable rails from the inner sides, substantially asset forth.

2. The combination in a switch of two di- Verging rails, intermediatemovable split rails 4, 5, 6 and 7, a shifting-bar to which rails 5 and 6are fastened, and having means for engaging and moving rails 4 and 7from the outer sides only, and a spring operating against the innersides of rails 4 and 7, sublo stantialiy as set forth.

In witness whereof I have afixed my signature in presence of twowitnesses.

JAMES D. BAILEY.
